Members of the signal transducers and activators of transcription (Stat) family regulate essential cellular growth and survival functions in normal cells and have also been implicated in tumorigenesis. We have studied the potential role of Stat5 in mammary tumorigenesis by targeting Stat5 variants to the mammary gland of transgenic mice using regulatory(More)
Signal transducer and activator of transcription (Stat5) is a transcription factor, which transduces extracellular cytokine and growth-factor signals to the nuclei of mammalian cells. As a major mediator of prolactin action, it is involved in the regulation of the development, function, and survival of mammary epithelial cells. The carboxyl terminal of(More)
A β-lactoglobulin (BLG)/luciferase gene vector (p907), composed of a luciferase intronless gene inserted between the second and sixth BLG exons was constructed. Stable transfections of CID-9 cells with this vector, as well as with a series of additional vectors, were performed to define regulatory regions within the BLG sequence, and the contribution of the(More)
Signal transducer and activator of transcription 5 (Stat5) transduces extracellular cytokine and growth factor signals to the nucleus of mammary epithelial cells and thereby regulates gene transcription during pregnancy, lactation, and weaning. Gene constructs were prepared which subject the wild-type Stat5 or a constitutively active variant of Stat5 to the(More)
